My experience with user defined functions has been limited to simple
procedures using individual data items as arguments. Now, I need to grab
a range of values from the SS, pass them to a function as one or more
arrays, read the arguments into local arrays withing the VBA procedure,
perform my process, and return the function value.

I need a simple illustration of this process but have had no luck with
the Excel/VBA help. Where should I look?

Here is a simple example

Function mySum(rng As Range) As Long
Dim ary
Dim i As Long
ary = rng
For i = LBound(ary) To UBound(ary)
mySum = mySum + ary(i, 1)
Next i
End Function
